GAS-STOVE.

SPECIFICATION forming part of Letters Patent No. 430,402, dated June 17,1890.

Application filed December 9, 1889. Serial No. 333,025. (No model.)

To all whmn it may concern:

Be it known that I, WILLIAM C. PERKINS, of New Haven, in thecounty ofNew Haven and State of Connecticut, have invented new Improvements inGas-Stoves; and I do hereby declare the following, when taken inconnection with accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in-

Figure 1, a View in vertical section of a gasstove embodying myinvention, the burner and the standard therefor being shown; Fig. 2, adetached plan View of the burner; Fig. 3, an enlarged broken view ininside elevation, showing the attachment of the burner to the standard.

My invention relates to an improvement in gas-stoves, the object beingto provide for equalizing the pressure of the commingled gas and airthroughout the burner and for preventing the'fiame from running, or, asit is termed, firing, back into the supply-pipe and burning thesupply-tube.

With these ends in view my invention consists in an inclinedbafile-plate located at the intersection of the supply-pipe with thebody of the burner.

As herein shown, the burner of the stove consists of an annular body A,provided with a supply-pipe B, having perforations G for the inlet ofair formed in it, and adapted at its outer end for the attachment of theflexible gas-supply tube D, of which a short section is shown. Aperforated annular ring E, secured to the said body A by screw-bolts F,completes the burner, which contains an annular chamber G for commingledgas and air. The said supply-pipe B has a transverse bar G, formedintegral with it andperforated at each end to receive screw-bolts H,passing through horizontal lugs *1 1, formed in the standard J onopposite sides of a slot K, made in the edge thereof to receive thepipe.

The construction above described is not of my invention, and is known tothe trade.

My invention resides in a baflie-plate L, made independently of theburner and located in the chamber G at the intersection thereof by thesupply-pipe B, and placed in an inclined position, its inner edge beingseated against the lower end of the inner wall of the body of the burnerand its outer edge extending upward and outward and meeting the upperedge of the outer wall of the body of the burner.

As herein shown, the baffle-plate is of segmental form to adapt itto anannular body, to which, however, its use is not limited. It maytherefore have different forms, although it will retain its location anddeflecting position. As herein shown, its ends are notched to permit thefreer escape of gas and air from under it; but the notches are notessential, and I do not limit myself to them. As the gas enters thesupply-pipe from the gas-supply tube it is met by currents of airpassing in through the perforations in the pipe through which the gasand air commingling flow. When the mixture strikes the inclinedbaffle-plate, it is deflected by the same in opposite directions andescapes in opposite directions under the ends thereof. The baflie-platetherefore acts to divert the mixture from the point where it enters theburner and equalizes its pressure throughout the same; but for the platethe pressure would be stronger at the said point than elsewhere and theaction of the same would be uneven. Some of the mixture flows back overthe plate and, escaping through the perforations in the.

ring, burns on the outer surface thereof; but the plate always standsbetween the .jets of flame and the incoming stream of commingled gas andair and prevents the flame from running or firing back into thesupply-pipe, as often happens in gas-stoves of the type to which minebelongs as they are now constructed. With my improved baffle-plate theburner may be lighted at any point on the ring, whereas under the priorconstructions referred to particular care must be taken in lighting theburner to prevent the flame from firing back.

By locating the baffle-plate in an inclined position, as described, thecommingled gas and air is thrown down upon the bottom of theburner-body, and thus more evenly diffused therein prior to burning thanwhen deflected laterally by a vertical bafile-plate. The describeddiffusion of the commingled gas and air secures an evener pressurethereof in the burner-body than is had with a vertical plate and theaction of the stove made more steady and uniform; but perhaps the mostimportant advantage derived from locating the bafileplate in an inclinedposition is that of preventing the flame from firing back' into thesupply-pipe and igniting the gas there, this being made impossible bythe inclined plate, which cuts oif communication between the adgacentholes in the ring and the supplyplpe, the jets from these holes beingthe ones which ignite the gas in the pipe.
